About this trial

Testicular tissue cryopreservation is an experimental procedure where a young boy's testicular tissue is retrieved and frozen. This technique is reserved for young male patients who are not yet producing mature sperm, with the ultimate goal that their tissue may be used in the future to restore fertility when experimental techniques emerge from the research pipeline.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Be male at any age.

Be scheduled to undergo surgery, chemotherapy, drug treatment and/or radiation for the treatment or prevention of a medical condition or malignancy with risk of causing permanent and complete loss of subsequent testicular function.

Or, have a medical condition or malignancy that requires removal of all or part of one or both testicles.

Have newly diagnosed or recurrent disease. Those who were not enrolled at the time of initial diagnosis (i.e., patients with recurrent disease) are eligible if they have not previously received therapy that is viewed as likely to result in complete and permanent loss of testicular function.

Disqualifiers

Diagnosed with psychological, psychiatric, or other conditions which prevent giving fully informed consent.

Diagnosed with an underlying medical condition that significantly increases their risk of complications from anesthesia and surgery.
